ALPHEUS W. ALTORFER, OF PEORIA, ILLINOIS, ASSIGNOB TO ALTORFER BROS. COM- PANY, OF EAST PFAJRIA, ILLINOIS, A. CORPORATION OF ILLINOIS.

Application filed April 23, 1923. Serial No. 634,149.

To all whom it may concern:

Be it known that I, Anrrmus W. Arron- FER, a citizen of the United States, a resident of Peoria, in the county of Peoria and State of Illinois, have invented new and useful Improvements in Wringers, of which the following is a specification.

This invention has reference to wringers,

and it has for its principal object to provide a quick releasing means for the compression on the wringer rolls in the event of a person accidentally getting the fingers or hand caught between the rolls, or in the event of fine fabrics becoming entangled.

The invention has for a further object to improve the construction of the wringer frame, and including therein the improved releasing means for the wringer rolls.

That the invention may be more fully understood reference is had to the accompanying drawings forming a part of the description, which illustrates a preferred embodiment of theinvention, and in which Figure 1 is a side elevation partly in section, showing a wringer embodying my invention;

Figure 2 is an end view of Figure 1;

' Figure 3 is a view similar to Figure 1, except that the releasing means has been operated to release the compression on the wringer rolls;

Figure 4 is a cross-section as the same would appear if taken on the line 44 Figure 3;

Figure 5 is a cross-section as the same would appear if taken on the line 5-5 Figure 3; and

Figure 6 is would appear, Figure 3.

Like characters of reference denote corresponding parts throughout the figures.

The frame of the wringer includes the a cross-section as the same if taken on the line 66 duplicate sections 1, 1 preferably made of metal, although they could be made of other material. Said sections are formed at their opposite ends with the upstanding and matching semi-spherical bodies 2, 2 which when the said sections are joined or secured together form barrels which encase the compressing means for yieldingly holding the wrin er rollers in coacting relation. Said barrfis have preferably open upper ends and closed lower ends, as'shown. At one end of through reach the frame housing extensions 3, 3 are provided, which, together enclose the gears for the rollers. The barrels of the wringer frame are connected by the reach members 4, 4 and 5, 5 which unite in a central body pr zframepart 6, 6 and the reach members The driving and driven wringer rolls are designated 8 and 9 respectively. The roller 8 having a shaft extension 10 which passes out of the wringer frame and into a gear casing 11 which encases gearing not shown, for operating said shaft from a suitable source of power. The two rolls 8 and 9 have shaft extensions 12 and 13 respectively, journaled in the housing 3 and carry the intermeshing gear wheels 14 and 15. The roller 9 has a shaft extension 16 journaled in that end of the frame carrying the shaft 10 of the roller 8.

In each barrel of the frame bearing blocks 17 and 18 are provided for the shaft extensions of the rollers 8 and 9 and injuxtaposition to each block 18 is a plate 19 formed or provided with a stud 20, and bearing against each plate 19 and encircling its stud 20 is a coil spring 21, which also assumes an upstanding position in the barrel, and the upper ends of said springs also encircle studs 22 on plates 23 similar to the plates 19. Said plates 23 and approximately the upper half portions of the springs 21 are carried in inverted cup-like sleeves 24 carried in the upper ends of said barrels. Having a threaded connection with the upper closed ends of saidsleeves 24 are thum screws 25 which engage with the plates 23 for the purpose of adjusting the osition of the plates 23'and increasing or ecreasin the tension in the springs 21. The barreTs at their upper ends are chambered, as at 26 to receive a flange 27 on the lower ends of the sleeves 24, and also coil springs ,28 which normally rest on said flanges 27 and act as a cushion in a manner to be explained.

The sections of the wringer frame are 'oined when placed together by means of bolts 29 passing through the walls of the barrels and between the shaft extension of the rollers 8 and 9; also by a bolt 30 passing through the central body or frame part 6, and by short pins or spindles 31 passlng members 4, 4 which serve as fulcrum pins or members for levers to be described. The sections .of the frame part 6 are formed or provided with the upstanding matching ears 32, to which has a pivotal connection a lever to be described. 33, 33 designate a pair of similarly constructed levers which are fulcrumed on the pins or spindles 31. The short arms 34 of said levers normally overlie and bear down against the upper closed end of the sleeves 24 in the'barrels of the wringer frame, while the long arms 35 of said levers are lifted and held raised by the cam like shoulders 36, 36 on a .lever 37 having a bifurcated end 38 which straddlesand is pivoted to the ears 32 on the frame part 6. In the position of the levers 33, 33 just stated, the cushion springs 28 rest idly on the flanges 27 of the sleeves 24, and only act to cushion the thrust of the sleeves 24, when the lever 37 is moved downwardly releasing the sleeves 24 permitting the springs 21 to expand and relieve the pressure on the wringer roll 9.

While I have shown the gear casing 11 attached to the wringer, and wringer and casing swingable on a post or stand, no

claim is made in this application to such structure and the same, therefore, need not be further described or detailed.

Assuming now that the parts are in the relative positions shown in Figure l of the drawing with the wringer roller surfaces in contact, compression being applied through the coil springs 21, and the person operating the wringer getting his or her fingers between the rollers, or fine fabrics ecomingentangled, such operator with the other hand will grasp the lever 37 drawing it down from the position shown in Figures 1 and 2 to the position shown in Figures 3 and 4. Such movement of the lever 37 moves the cam like shoulders 36 from beneaththe long ends 35 of the levers 33 permittingthe coil springs 21 to expand forcing upwardly the sleeves 24 whichwill. release the tension and pressure on the roller 9, that it may be lifted away. from the roller 8, see Figure 3. As the levers 33 are oscillated under pressure of the springs 21 the short ends 34 of said levers move out of the path of the sleeves 24 but not out of the path of the cushion springs 28, which'are lifted by the flanges 27 on the sleeves 24 when the latter are raised, and .said springs 28 engage with the short ends 34 of the levers .33 stopping the upward movement of the sleeves 24, in a cushion like manner and without ar. 0 v

To return the parts to their normal operative positions the sleeves 24 are again depressed to a position which will permit the levers 33 to again en age the same upon the raising of the lever 3 which, as it is raised, will cause its cam like shoulders 36 to ride under and hold the long ends 35 of the levers 33 raised, as in Figures 1 and 2. To relieve the tension in the springs 21 the thumb-screws 25 may be unscrewed; like, wise screwing them down will increase the tension.
